The miniature touch switch is small in size and small in contact resistance. It has a crisp feel when swinging. It has a wide range of sizes and types. It is loved by many industries in the market. It is widely used in many industries, such as automobile industry, medical equipment, digital products, home movies, mobile phones, etc.
1. The storage condition of the three-layer insulating wire is that the ambient temperature is -25 C~30 C, the relative temperature is 5 ~75, and the storage period is one year. It is forbidden to store three layers of insulating wires in high temperature, high temperature, direct sunlight and dust environment. Insulation breakdown voltage, withstand voltage and windability test must be done again for three-layer insulated wires beyond storage period before they can be used.
2. Attention should be paid to the following points when winding micro-touch switch: the three-layer insulation wire is strengthened by film. If the film is seriously deformed or damaged by mechanical or thermal stress, the safety standard cannot be guaranteed; there must be no burrs on the transformer skeleton, the corner of the contact wire should be smooth, and the inner diameter of the outlet nozzle should be two or three times the outer diameter of the wire; the end of the cut wire should be very sharp and not close to the film of the wire.
3. There are two kinds of devices which need three layers of insulation when peeling the film. One is a static solder tank, which is suitable for welding three layers of insulating wires below 0.40MM. When soldering, moving horizontally in the solder groove and shaking the coil skeleton, the soldering work can be completed in a short time. Another welding device is a jet solder tank with air cooling, which can weld multiple coil skeletons at the same time and is suitable for mass production.
